AL1512-B 15 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=12 mm; NA=0.55 AR 650-1050nm

The AL1512-B is a high-precision aspheric lens, meticulously crafted by Thorlabs, a renowned vendor in the optical industry. This lens boasts a 15 mm diameter and is constructed from S-LAH64, a high-quality material from Ohara. The lens is designed for use with a wavelength of 780 nm, making it suitable for a wide range of applications.

The lens features an effective focal length (EFL) of 12 mm, which is crucial for determining the lens's magnification power and field of view. The EFL, combined with the lens's high numerical aperture (NA) of 0.55, allows for a wide angle of view and high light-gathering capability, making it ideal for imaging and laser applications.

The aspheric design of the lens is achieved through a series of complex mathematical calculations, resulting in a surface that deviates from a simple sphere. This design significantly reduces spherical aberration, a common issue in traditional lenses, thereby improving image quality and resolution.

The lens is CNC polished, ensuring a smooth, high-quality surface finish. It is also coated with a broadband anti-reflection (AR) coating, optimized for the 650-1050 nm range. This coating reduces surface reflections, enhancing transmission and minimizing losses, thereby improving overall system performance.
